BREATH DETECTOR.

Application filed November 12, 1923. Serial No. 674,186.

To all'whom it may concern i Be it known that I, GEonGE STARR lVHITE, a citizen of the United States, and resident of Los Angeles, in the county of Los Angeles', State of California, have invented new and useful Improvements ina Breath Detector, of which the following isa speci fication.

Bodily sensations are dependent upon the ness of the contact. However, if the object is brought'to the subject so as to cause impact, the degree of consciousness is intense. Gradually changing the temperature of an object in contact with a. subject does not have much of a sensory effect. A sudden change, however, has a verynoticeable effeet. A subject does not notice the odor of an object having a like odor to that which he has been smelling. -However, a sudden change of odor is very noticeable. Thus, a

subject who v-hasbeen eating onions will not notice the 1 odor of the, breath of another who has also eaten onions. A subject under normal conditions does not smell his own breath. I have found upon experiment that if a subject collects his exhalations in a container and then suddenly expels them intolllS own face or nostrils, he will be able to smell his breath. This is due to the sudden-' ness of the change, there being an increase in volume and impact of gas or vapor conc trated wherein:

taining thev odor. Upon tihese premises, I have constructed a device for a subject to detect the odor of his own breath.

An embodiment of my invention is illusin the accompanying drawing,

Fig. 1 is anelevation of a detector in expanded condition, a portion of the bellows being broken away to show the interior;

Fig. 2 is an end View looking in the direc tion of the arrow 2 of Fig. 1; and Fig. 3 is a perspective View of the detector in collapsed condition. r

Referrin more particularly to the drawing, a rigi head is indicated 'by' l. In the form shown herein, this head is circular and may be made of metal. A suitable metal is tin, aluminum, or a ,tin ..p1ate.' Tin and aluminum have 'no odor of their own nor do they absorb other odors. Attached to the head 4 is a bellows 5 formed of some pliable material which will not retain odors orhave a distinctive odor of its own such as" a gelatinized paper. At the other end is a "head 6 of material such as .head 4 is formed of buthaving an opening at the The device is operated in the following manner: It is collapsed as shown in Fig;

3. The subject then places the mouthpiece between the lips, inhales through the nose and exhales through-the mouth, repeating this several times until the bellows have been expanded. The detector is thus filled with matter having the odor of the oral and nasal passages. If inhalation is through the mouth alone, only the odor of the oral passages will be detected. Thereupon, the bellows is collapsed so as to expel the gases and vapors, the mouthpiece being pointed toward the nostrils and the expulsion is effected suddenly. A subject may perfume the .breath to determine whether a proper perfume for producing a desired odor is secured, and may use the detector to test the breath. In some instances it may be found desirable to have the detector impregnated with a certain odor in order to differentiate or contrast odors. Cellulose materials, if used, serve to collect the moisture of the breath in which the matter that gives the odor is suspended. I have herein shown the chamber as collapsible, this being one form of a chamber wherein the gases or vapors taken'in may be The expulsion being effected in the opposite directions. However, there are various equivalents of the specific form shown how in as will be apparent from the definition of the invention contained in the appended claims.

What I claim is:

1. A breath detector comprising a dis' v the expulsion of said gases or vapors.

2. A breath detector comprising a disp cement chamber of collapsible form having Walls of material substantially non-1e tentive of extraneous odors, and a tubular member [freely communicating therewith serving as a mouthpiece for admission of exhalation gases or vapors and a nozzle for the expulsion of said gases or vapors.

w 3. A breath detector comprising a displacement chamber having Walls of mate- -rial substantially non-retentive of extrane-' ous odors, said displacement chamber being formed with a bellows and a tubular member freely communicating therewith serving Jis a mouthpiece for admission of exhalation gases or vapors and a nozzle for the expulsion of said gases or vapors. I

4:. A breath detector comprising a displacement chamber having walls of material substantially non-retentive of extraneous odors, cellulose material loosely placed 'therein, and a tubularimember freely com lnunicating therewith serving as a mouth piece for admission of exhalation gases or vapors and a nozzlefor the expulsion of said gases or vapors.

In witness that I claim the foregoing I, have hereunto subscribed my name this 31st day of October, 1923.

GEORGE STARR WHITE.
